Explanation: The migration of Chinese to US started far back middle of 19th century. Throughout the first half of the 19th century, Chinese manual laborers (predominately men) migrated to the West Coast, where they found employment in agriculture, mining, railroad construction, and other low-skilled jobs. In response to negative public sentiments and organized labor lobbying, Congress in 1882 passed the Chinese Exclusion Act, the first legislation aimed at excluding certain foreigners based on their origin.
